Gemini 3.1 Flash Lite Image

Nano Banana Lite is designed as the efficiency specialist of the image generation family, offering ultra-low latency and cost-effective image generation and editing. By targeting a sub-2 second latency and significantly reduced TPU compute costs, this model enables high-volume interactive developer use cases and real-time consumer applications.

Key capabilities:

  • Sub-2 second end-to-end latency
  • Interleaved generation and editing with native support for Text -> Text + Image(s) and Image + Text -> Text + Image(s).
  • Optimized for lower resolutions of 1K (1024x1024px).
  • Supports a discrete set of 14 aspect ratios including standard formats.
  • Fast multi-turn local edits (swapping colors, sticker creation, background adjustments).
  • Maintains high character alignment matching original Nano Banana standards.
  • New 1:1, 3:2, 2:3, 3:4, 4:3, 4:5, 5:4, 9:16, 16:9, 21:9 aspect ratios.
  • Supported image_size values: 1024px (1K). (Note: 2K and 4K are unsupported).
  • SynthID (Always On) + C2PA watermarking.
